If you don't want to give any positive input why bother giving any input?

Just like to state, that I don't go around telling people how hard I worked or tired my hand on something. So I did not see the need to tell everyone this in the beginning so I am not sure maybe it should be protocol?

well its not like I just jumped onto this forum to ask for help, I did spend time on studying he example code and got the drawline working for GDI by modifying the sample codes. I spent more than the better half of 2 days

If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about?
Help me to understand what I'm saying, and I'll explain it better to you
“The First Rule of Program Optimization: Don't do it. The Second Rule of Program Optimization (for experts only!): Don't do it yet.” - Michael A. Jackson

void threadFunction(void *argList)<br />
{<br />
    // Process on varibles.<br />
    _endthread();<br />
}<br />
void className::methodName()<br />
{<br />
    int x = 100;<br />
    _beginthread(&threadFunction, 0, /*what i have to pass over hear*/)<br />
}

void className::methodName()
{
int x = 100;
_beginthread(threadFunction, 0, this)
} 

void threadFunction( void *p )
{
if ( ! p ) return;
className * pClass = (className *) p; // maybe a convenient alias
pClass->m_count++; // where count is class public int data
...
}

BTW In fact there is a direct solution of your problem, and it is so ugly that I cannot resist the temptation to post it :

[modified afterwards Cedric Moonen reply  :-O ].
//-> HERE STARTS BAD CODE
class className;
struct MyUglyThreadArg
{
 className * pClass;
 int * px;
};
class className
{

  ...
  MyUglyThreadArg muta;
  void methodName()
  {
    static int x = 100;
    muta.pClass = this;
    muta.px = &x;
    _beginthread(&threadFunction, 0, &muta);
  }
...
}; 

void threadFunction( void *p )
{
  if ( ! p ) return;
  MyUglyThreadArg *pMuta = (MyUglyThreadArg *) p;
  className * pClass = (className *) p->pClass; 
  pClass->m_count++; // where count is class public int data
  *(pMuta->px) = 200; 
...
}
//<- HERE ENDS BAD CODE
